MPC5746R ECC ISSUE

Can anyone give me a solution or documentation about ECC?

My current solution is

   Write different data to the same address and then read the address, this operation will trigger the IVOR2 interrupt, record the fault in the interrupt and clear the flag bit, exit the interrupt and erase the FLASH in the idle time.

    But C55FMC_MCR.EER cannot write 1 to clear, it will recover from 0 to 1.

And it's the same as MEMU.

Hi, pay attention to following appnote, I have recently shared:

https://community.nxp.com/docs/DOC-339955 

It is written for MPC5744P, but several sections speak about MPC57xx overally.

 

Hope it helps
